People hope electric fan in the small volume, convenient, etc, and on the basis of to have more features, and the wide application of infrared remote control and single chip microputer technology maturity, it makes the infrared remote control system bee the trend of the development of electric fans. This design scheme based on the demand of the market, bined with infrared remote control design is simple, convenient, low cost and other characteristics, the use of a special radio transmission HS0038 receiver chips, and based on this, designs a simple system of infrared remote control electric fan. System including receiving and launch of two parts, this paper designed the basic functions of the electric fan: switch function, category five speed adjustments. After many tests and circuit adjustment, the system can realize the functions are normal.
